If c=12 find a right triangle 90 degrees 45 degrees 45 degrees

If is a triangle 90°, 45°, 45° then the sides are in ratio 1 : 1 : √2.

If c = 12 is a hypotenuse, therefore we have the equation:

If c = 12 is a leg, therefore we have:

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
